Why should pig pen floors not be paved with concrete?
Summary Effects on pork quality: the friction of a concrete floor is relatively high, so it causes the pigs' skin to become rough. Effects on the pigs' limb health: the concrete floor of the pig house is relatively hard, so the pigs' limbs are more prone to wear. Effects on the pigs' growth rate: pigs grow better in an environment where they are in natural contact with soil

The correct injection sites for pigs and the reasons for bleeding after injection
Summary Intramuscular injection: the injection site is chosen at the well-muscled buttock or neck. Subcutaneous injection: the injection site is chosen at the inner thigh or behind the base of the ear. Intravenous injection: the injection site chosen is the back of the ear or the great auricular vein. Intraperitoneal injection: inject the

How to reasonably determine nitrogen fertilizer application rates in precision quantitative rice cultivation
The quantification of nitrogen needs to consider the fertilizer requirements of high-yield rice, the pattern of soil nitrogen supply, fertilizer characteristics and the current-season utilization rate, as well as various changes during the growth period, and includes two parts: total nitrogen quantification and nitrogen fertilizer application methods. Determination of total nitrogen amount: obtained through soil testing and fertilizer recommendation trials

What are the reasons for poor coloration and low sweetness in muskmelons
Muskmelons grown in plastic greenhouses are about to hit the market in large quantities. Every buyer hopes to buy muskmelons that are good in color, sweet and crisp, and farmers who grow muskmelons especially hope that their muskmelons will be liked by buyers and fetch a good price. Currently on the market

Reasons for Low Fruit Set in Muskmelon and Methods to Improve It
I. Reasons Why Plants Are Prone to Poor Fruit Set 1. Excessive vegetative growth or weak, spindly plants. During the growing period of muskmelon, applying too much nitrogen fertilizer or cultivating in a protected environment with high temperature and high humidity and poor ventilation prevents vegetative growth and reproductive growth from being coordinated, often resulting in excessive vegetative growth or weak, spindly plants.

How to Control the Alternate Bearing of Plum Trees? Practical Cultivation and Management Methods
1. Reasonable pruning to regulate tree vigor. On-year trees should be pruned early (before the onset of winter) and heavily. Remove dead branches, residual branches, slender branches, scorched-tip branches, diseased and pest-infested branches, and excessively dense, crossing branches. Do more heading back to stimulate shoot growth; for vigorous branches and competing branches, cut back hard, removing 2/3 to 3/4 of the branch or leaving only 3 to 5 buds. Thin flower buds early, prune away excess flowering branches, and reduce the fruit load. Off-year trees should be pruned late (around the beginning of spring), keeping flowering branches and thinning out non-flowering vegetative branches. Leave branches unpruned or bend them down to moderate tree vigor, retain as many flowers and fruits as possible, and increase the fruit set.

What are the causes of cotton square and boll shedding?
1. Physiological shedding. Physiological shedding accounts for about 60-70% of total square and boll shedding, mainly caused by improper management and damage from pests and diseases, which leads to nutrient imbalance in the plant and insufficient nutrients for squares and bolls. There are mainly the following three aspects: 1. Poor root development, insufficient absorption of water

How to Fertilize Tea Plants Reasonably? Detailed Methods and Techniques
Fertilizer is the food for tea plant growth and the material basis for increasing tea yield and improving quality. Therefore, fertilization plays an important role in the growth of tea plants as well as the yield and quality of tea. Good fertilization techniques can maximize the yield-increasing effect of fertilization, maintain

How to Use Biogas Fertilizer Reasonably in Citrus Planting
The biogas slurry and biogas residue produced after anaerobic fermentation in a biogas digester are a very good biological organic fertilizer, and are sterile, non-toxic and highly effective. Applied to fruit trees, they can improve quality and increase yield. The following technical recommendations are now proposed on how to reasonably use biogas fertilizer.

What to Do If Your Cherry Tree Won't Bear Fruit? Try These Solutions
There are many reasons for failure to bear fruit, specifically the following: 1. The climate may be unsuitable. 2. Improper cultivation and management, leading to excessively vigorous tree growth, with no flower buds formed, will also result in no fruit. 3. Severe pests and diseases or poor fertilizer and water conditions, insufficient stored nutrients in the tree, leading to poor flower bud development and severe flower and fruit drop during the flowering period; or due to continuous rainy weather or sudden low temperatures during the flowering period, resulting in poor pollination and fertilization.
